SPRING-MOTOR.

Specification of Letters Patent. Application filed March 18,

Patented June 26,1906. 1904:. Serial No. 198.814-

To all whom, it may concern;

Be it known that I, HARRY T. KINGSBURY, a citizen of the United States, residing at eene, in the county of Cheshire, State of New Hampshire, have invented certain new and useful Improvements in Spring-Motors, of which the following is a description, reference being had to the accompanying drawings and to the letters of reference marked thereon.

My invention relates to spring-motorsparticularly adapted to mechanical toys.

The object of the invention is to provide a simple and inexpensive motor in which the spring may be quickly rewound from the driving-axle. This object I accomplish by the construction shown in the accompanying drawings, in which Figure 1 is a side elevation of my improved motor. Fig. 2 is a plan thereof. Fig. 8 is a plan of a modified form. Fig. 4 is a sectional side elevation of the right side of Fig. 3. Fig. 5 is a perspective of a further modification, and Fig. 6 is a plan of a further modification.

In Figs. 1 and 2, A represents the driving-axle, carrying the ground-wheels A A and mounted to rotate in bearings A depending from the frame or part A The axle A is provided with a collar a and a fixed pinion I), spaced apart to receive a large gear-wheel a between, the gear a being loose on the axle and provided with a pawl c, engaging the pinion b. The pawl c locks the gear a to the axle when the latter is 1'0- tated rearwardly in the operation of winding the spring B. The gear a meshes into a small pinion d, loose on a short axle d, mounted at one end in the frame A and at its other end in an angle-bracket A depend ing from the frame A The pinion d meshes with a crown-gear e on the end of the longitudinal drum B, about which the helical spring B is coiled. One end of the drum is journaled in the bracket A and the other end is journaled in a bracket A One end of the spring B is secured to the crown-wheel e or to the drum B, while the other end is secured to the bracket A It follows, therefore, that when the axle A is rotated rearwardly by moving the ground-wheels quickly to the rear the pinion b will rotate the loose gear a rearwardly through the medium of the pawl c and the gear a will in turn rotate a pinion d, which in turn will rotate the crown- B upon the drum.

The winding mechanism having been described, I will now describe the transmission or driving mechanism. At one end of the pinion d is a large loose gear h, provided with a pawl f which engages the pinion d in such manner that when the pinion is being rotated by gear a to wind the spring the pawl will not lock the pinion (Z to gear h; but when l the winding has been completed and the I motor released the rearward rotation of the pinion (1 will engage the pawl f and carry it and the large gear 7t around to the rear, and as the large gear h meshes into the pinion 1), fast on axle A, the latter will be rotated in a forward direction, and so propel the toy to which the motor may be applied. In such forward rotation of the axle the pinion b is free to rotate without being locked by pawl c to the large winding-pinion a. The large gear a is thus idle in the unwinding of the motor-spring, and the large gear h is active, while in the winding of the spring the large winding-gear a is active and the large transmitting-gear h is inactive.

In Figs. 3 and 4 the drum B is journaled parallel with the axle A instead of at right angles thereto, as in Figs. 1 and 2, and both are journaled in bearings A". In these figures a is the large winding-gear loose on the axle A, b is a ratchet-wheel fast on the axle, and c is the pawl adapted to lock the gearwheel a to the axle when the latter is rotated rearwardly, but allow the axle free forward rotation. The gear-wheel a meshes with an idle pinion e, which in turn meshes with a pinion d loose on the axis of the drum B and having connected with it a flange (Z to which one end of the spring B is secured. Reverse movement of the winding-pinion d is prevented by a pawl f pivoted to the ame. The opposite end of the drum is provided with a fixed transmitting-gear W, to which the opposite end of spring B is secured, and this gear 7L2 meshes with a small gear g, fast on the axle. Thus after the spring has been wound by a quick rearward movement of the toy along the floor and the toy released the winding-gears will remain idle and the spring will rotate gear 7L2 rearwardly and it in turn will rotate pinion g and axle A forwardly.

In Fig. 5 the spring-motor is wound by the I wheel 0, and the latter will Wind the spring forward movement of the axle and groundwheels. In this form of the invention the I axle A is provided with a large loose windinggear a having its hub provided with a groove (L5 to receive the end. of a shiftinglever a. The inner face of the gear a is provided with two clutch-studs p p, while the axle is provided with fixed clutcharms a adapted to be engaged by the studs p p when the gear a is moved inwardly along the axle. The gear a meshes with a pinion d loose on the axis of the drum B and having a flange (F, to which. one end of the spring B is secured. Reverse motion of pinion d is pre vented by a pawl f, pivoted to the frame. The opposite end of the spring is secured to a large gear in, secured to that end of the drum and meshing with a small pinion g, fast on the axle. Thus when the axle is clutched to the large gear a and rotated forwardly the spring will be wound, and then by unclutching the axle and gear a the gear 7L will rotate rearwardly, and so impart forward. rotation to the axle.

In Fig. 6 a further modification is shown, and the drum or core 13*, about which the spring B is wound, is bent upon itself. This bending of the drum may take any form that will allow of the winding and unwinding of the spring. The purpose of the bending or curving of the drum or core is to allow of a greater length of spring in a given space than woul l be possible with a straight drum or core. This is particularly advantageous in toys where there is only space suflicient for a short length --of drum, and by bending the drum or core upon itself, as in Fig. 6, twice the length of spring may be employed, and so the vehicle will be propelled twice the distance.

The core or drum B is supported in any suitable manner from the vehicle-body, and the springis secured. at one end to the drum or core and at its other end connected to a flanged pinion (Z loose on the laterally-bent end B of the core or drum. The axle A is provided with a large loose gear-wheel 0, having a pawl 0 to lock it to a small fixed pinion I), said large gear meshing with the flanged pinion cl, so that when the axle A is rotated rearwardly the pinion b will carry large gear a rearwardly, and this in turn will rotate pinion forwardly, and so wind. the spring. Reverse action of the spring will rotate pinion d, which will in turn rotate a large transmission-pinion 71. by means of a pawl f and. the large pinion 7L meshes with the small pinion b and so rotates the axle forwardly.

I do not restrict myself to the particular mechanism shown, as the same may be modified without departing from the scope of my invention. It will be seen that in the sevmediate pinion in eral forms of the invention the rewinding of the motor 18 far more quickly effected than would be the case where the winding is effected by merely reversing the motion of axle and the usual train of propelling-gears, as the latter operation is necessarily very slow.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is
